Glucosinolates and sinapine in camelina meal

Forty seven accessions of camelina (Camelina sativa L. Crantz) were analyzed for glucosinolates (GSLs) and sinapine in defatted meal. These antinutritional compounds are undesirable in camelina meal for use in animal feeding and therefore we show their variability to identify the best varieties for future breeding programs. Total GSLs ranged from 19.6 to 40.3 mmol Kg-1 dry weight (DW) with an average of 30.3 mmol kg-1 DW. Great variability has also been observed in the levels of individual GSLs (GSL1, GSL2 and GSL3), so that the content of GSL1 and GSL3 were not correlated to each other in the accessions of camelina. Five out of six winter forms of camelina showed low content of GSLs. Sinapine ranged from 1.09 to 4.75 g Kg-1 DW with an average of 2.57 g kg-1 DW. The sinapine content was not correlated with that of GSLs. The use of camelina meal is only limited by the presence of GSLs while sinapine content can be ignored in camelina varieties.
